In this paper, we propose a mechanism that reduces useless responses for RFID systems in the Internet of Things (IoT) environment, for tracking applications. The mechanism achieves its objectives by reducing the number of packets exchanged between readers and tags. We analyze the behavior of our proposal by considering the average number of identification rounds. With extensive simulations using an RFID module for the ns-2 simulator, we show the benefit of the proposed mechanism. When compared to the Pure Q Algorithm and Binary Tree Slotted Aloha, our mechanism reduces the number of packets up to 43%, which is a good result in terms of performance of IoT applications and energy consumption of the devices used in the communications.
